3. How will you prove that air supports burning?
Place two candles of the same length on a table. Light both candles. Cover one of the candles with an inverted glass tumbler. We can observe that the candle covered with the glass tumbler got extinguished after some time, whereas the other candle continued burning. The candle gets extinguished because the air component inside of the glass tumbler, which supports burning, is limited. Most of the component is used up by the burning candle.
However, the other candle is getting a continuous supply of air. This component of air, which supports burning, is known as oxygen.

4. How will you show that air is dissolved in water?
Take some water in a container. Heat it slowly on a tripod stand. Before the water begins to boil, look at the inner surface of the container. We observe tiny bubbles inside.
These bubbles come from the air dissolved in water. When you heat the water, to begin with, the air dissolved in it escapes. This experiment concludes that air is present in the water.
5. Why does a lump of cotton wool shrink in water?
The lump of cotton wool shrinks in water because the air inside the cotton lumps is replaced by water which makes the layer stick together.
6. The layer of air around the earth is known as ___________.
The layer of air around the earth is known as
atmosphere
.

7. The component of air used by green plants to make their food is ___________.
The component of air used by green plants to make their food is
carbon dioxide
.
8. List five activities that are possible due to the presence of air.
The five activities that are possible due to air are as follows:
-
Photosynthesis
-
Cloud formation
-
Respiration
-
Transpiration
-
Winnowing
9. How do plants and animals help each other in the exchange of gases in the atmosphere?
During the process of respiration, animals and plants consume oxygen from the air and release carbon dioxide gas into the air. Besides, green plants also release oxygen gas by utilising carbon dioxide during the process of photosynthesis. Hence, in this way, plants and animals help each other in the exchange of gases in the atmosphere.

Q6. How can you demonstrate that air supports burning, as discussed in Chapter 15 of NCERT Solutions for Class 6 Science?
To demonstrate that air supports burning, place two candles of equal length on a table. Light both candles. Cover one candle with an inverted glass tumbler. Observing the experiment, you will notice that the candle covered with the glass tumbler eventually goes out, while the other candle continues to burn. This happens because the air component supporting burning inside the glass tumbler is limited, as most of it is consumed by the burning candle. The continuous supply of air allows the other candle to burn, and this air component supporting burning is known as oxygen.
Q7. How does an organism living in soil breathe?
Through air present in soil.
Q8. How can you show that air is dissolved in water?
Take water in a pan and heat it. After sometimes just before it boils we can observe some bubbles at the inner surface of the pan. This is because of the air dissolved in water.
NCERT Solutions For Class 6 Science Chapter 12
Q9. Why does an animal living in soil come out of soil for respiration in the rainy season?
When it rains heavily, water fills up all the spaces occupied by the air in the soil. Therefore, organisms living in soil have to come out for respiration.
Q10. Why does a lump of cotton wool shrink in water?
A lump of cotton wool shrinks in water because water fills up the empty space that the air has occupied.
